Brock was the first opponent in the Gym Leader Castle of ''[[Pokémon Stadium]]''. His Pokémon, based on his roster in the original games combined with some from his anime roster, were Onix, Graveler, [[Cubone]], [[Vulpix]], [[Omanyte]] and [[Kabuto]] in the first round; and Onix, [[Golbat]], [[Golem]], [[Ninetales]], [[Dugtrio]] and Omastar in the second round. Oddly enough, many of these Pokémon (such as the evolved forms of Omanyte and Kabuto) later appeared on his roster in ''Gold'' and ''Silver''. In ''[[Pokémon Stadium 2]]'', Brock was the first opponent of the Kanto Gym Leader Castle. He used a [[Golem]], Onix, [[Pinsir]], Omastar, Kabutops and [[Forretress]] in Round 1, and a [[Slowbro]], [[Rhydon]], [[Steelix]], [[Shuckle]], [[Heracross]] and [[Ursaring]] in Round 2.

Brock was featured in ''[[Pokémon Masters EX]]'' as part of a playable sync pair with Onix. There was also a Sygna Suit variant paired with [[Tyranitar]]. He and [[Misty]] were the first two trainers to join [[Scottie/Bettie|the player's]] team for the [[Pokémon Masters League]] during the Main Story's introduction. He initially acted like a mentor to Scottie/Bettie, but he temporarily split off for the first Interlude chapter (between Chapters 10 and 11). In that chapter, Brock decided to challenge Scottie/Bettie to a battle as a fellow trainer because of how skilled they had grown and donned a new outfit called a sygna suit that enhanced his connection to his Pokémon. After being defeated, he accepted that Scottie/Bettie had learned everything that he could teach him, and he decided to rejoin the team as an equal teammate, rather than as a mentor or coach. Brock also made some appearances in the Main Story's Villain Arc, where he helped out during some of the conflicts against villainous organizations on Pasio. Brock was also featured as an opponent in a sync pair story, where [[Nate/Rosa|Rosa]] had to defeat him in order for her [[Servine]] to evolve, and he made minor appearances in a number of Story Events.

*Brock also served as a major supporting character in the ''Pokémon'' anime series. After Ash defeated him at the Pewter Gym, Brock left the gym in the care of his parents (and later his younger brother Forrest) to travel with Ash in hopes of achieving his dream to become a master Pokémon breeder. Along the way, he showed his talents as a chef and was known for being flirtatious with nearly every girl he encountered (with limited success). Brock has been the most loyal of Ash's traveling companions, remaining with him in the journeys through Kanto, [[Johto]], [[Hoenn]] and finally [[Sinnoh]]. Until that point, he was only absent for the filler series involving the exploration of the Orange Islands (between the Kanto and Johto episodes), when he briefly worked as a lab assistant for Professor Ivy. Towards the end of the Sinnoh episodes, Brock developed an interest in becoming a Pokémon doctor and stayed behind in Kanto to train for that. His place in Ash's crew was originally taken by [[Cilan]] for the following Unova series. Brock has since made several guest appearances, including a two-part episode of the ''Sun and Moon'' series which featured him and Misty reuniting with Ash.

*Brock appears in the ''Pokémon Adventures'' manga. In the ''Red''/''Blue''/''Green'' arc, he works in conjunction with [[Misty]] and [[Erika]] (and later [[Blaine]]) as the only "good" gym leaders battling against Team Rocket. He is shown to battle shirtless, and as in most adaptations, he befriends Red after being defeated by him. He and the other good gym leaders lend Red their aid at several points in the series and then do the same for Yellow in the ''Yellow'' arc. In that latter arc, Brock ultimately ended up defending Pewter City from the Elite Four's attack. In the ''Gold''/''Silver''/''Crystal'' arc, Brock and Misty helped Red to prepare for his gym leader examination, and during the competition against the Johto gym leaders, he was defeated by [[Jasmine]]'s newly-discovered [[Steelix]].

*In the ''Yellow'' version and ''Let's Go!'' games, he mentions his dreams of becoming a Pokémon breeder. This references his aspirations from the Pokémon anime. The latter games also reference his tendency to be rejected by girls from the anime.
